The current structure of healthcare coverage in the United States has a combination of employer-based coverage and public program (e.g., Medicare, Medicaid) coverage, with a large uninsured population. If a single-payer system is implemented where Medicare is expanded to cover all citizens for those who prefer private insurance, there will be comparable coverage under the same range of private insurance plans already available. Keeping in mind these considerations, answer the following questions:
1. What do you think about allowing some people to purchase additional insurance, thereby creating a two-tier health system based on affordability?
2. What are the advantages and disadvantages of this initiative?
